Cubital tunnel syndrome is compression or irritation of the ulnar nerve behind the inside of the elbow. It commonly causes numbness and tingling in the little and ring fingers, often worse when the elbow is bent.
Cubital tunnel syndrome occurs when the ulnar nerve is compressed or irritated where it passes behind the bony bump on the inside of the elbow — the spot many people know as the “funny bone.” It is the second most common nerve entrapment in the arm after carpal tunnel syndrome.
Assessment focuses on confirming the ulnar nerve as the source, checking for weakness or muscle wasting, and considering other causes such as a neck (cervical) nerve problem when the pattern is unclear. Nerve conduction studies help grade severity and guide whether specialist referral is needed.
First-line care is usually activity modification, ergonomic changes, avoiding leaning on the elbow, and night splinting to keep the elbow straight, sometimes with nerve-gliding exercises. Progressive weakness or established muscle wasting needs timely review, as prolonged compression can become harder to reverse and may warrant surgical assessment.
Evidence-informed treatment summary
How our treatment options may fit for Cubital Tunnel Syndrome
The options below include the treatments offered at The Back Pain Doctor. Listing a treatment does not mean it is recommended for this condition. The evidence, likely benefit and role of each option are considered against the diagnosis, examination findings, imaging where appropriate, patient goals, risks, cost and alternatives.
Foundation
Diagnosis, education and progressive rehabilitation
This is the starting point for most musculoskeletal conditions.
The priority is to identify the likely pain generator, explain the condition clearly, modify aggravating load and build a realistic plan to restore strength, movement and confidence.
Evidence is condition-specific; it is not a universal pain treatment.
Shockwave is best framed as an adjunct where the diagnosis fits. It is generally more established for selected tendon and plantar heel pain presentations than for many joint or nerve conditions.

→ Evidence varies substantially by condition, tissue and preparation method.
PRP may be discussed in selected tendon or joint presentations. It should not be presented as a guaranteed regenerative treatment, and uncertainty, cost and alternatives should be discussed.

→ Best used for specific inflammatory or irritable pain generators, usually for short-term relief.
An injection may help when a joint, bursa, tendon sheath or other defined structure is driving symptoms. It is not a cure and needs to be weighed against risks, recurrence and the need for rehabilitation.

→ Clinical evidence is still developing and guideline support is limited.
EMTT may be discussed as an adjunct in selected presentations, but should be presented with clear uncertainty and never as a replacement for diagnosis, load management or rehabilitation.

→ Evidence is condition-specific and generally less established than exercise-based care.
Prolotherapy may be considered in carefully selected chronic ligament, tendon or joint-related pain presentations, but it is not a first-line treatment.

→ Most relevant when focal myofascial pain is a clear contributor.
Trigger point treatment may reduce pain from focal muscle spasm or myofascial tenderness. It should be paired with movement restoration, strength work and recurrence prevention.

→ Relevant only when the history and examination support nerve irritation or entrapment.
Nerve-focused treatment may be discussed when there is a plausible peripheral nerve pain generator. Progressive weakness, major neurological deficit or red flags require a different pathway.

This is general information only. Suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of uncertainty, expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
